Tony aka Eddy's older brother never believed in ghosts, he always thought that they were things that were made up by crazy people that wanted attention or from stories that would scare little kids. Yes Tony never believed in ghosts and never will, until after the day he murdered his little brother and his stupid pals.
It happen during the day that his parents had decided to kick him out after he got caught vandalizing the school as well as stealing money from a local bank. He was so angry that day that something inside him snapped, he desperately wanted to take his anger out on someone and unfortunately on that day the first three people he saw were his younger brother and his two pals who were watching television.
He told them that he had something to show them in his room, they instantly took the bait as they always wanted to go into his room, but were usually told to stay out by him, so they obliviously jumped to go in on the opportunity.
When they entered the room their eyes went as wide as pancakes over the stuff that were in the room. But that wonder quickly disappeared when Tony shut the door and locked it with its various locks, they turn around in confusion and saw Tony staring at them with anger in his eyes.
Tony killed them right then and there in that room, he stabbed Double Dee multiple times with a steak knife, strangled Ed with rope, and lastly for Eddy he gave him a severe beating, before he gave the finishing blow to his brother the last thing he said to his battered brother was "I'm finally going to get rid of the mistake in the family." He then grabbed his neck and snapped it, to make it worse he stood over their corpses and spit on them, and left the room as if he was casually going to the bathroom.
He was already out of Peach Creek by the time his parents discovered their bodies, he decided to sleep at a motel for the night. The activity started the next day, when Tony woke up the first thing he noticed was an unpleasant smell in his room; he complained to the manager but when he came to see where it came from he couldn't smell anything. Tony insisted that there was a horrible smell, the manger thought that he was playing some short of particle joke so he gave him a scolding and left leaving him to the horrible smell.
The next strange thing that happen was that after he took a shower his clothes were neatly folded on the bathroom sink, which was weird since he could've sworn that he had them thrown on the floor. He puts them on and exits the bathroom where he saw a piece of paper on his suitcase, he picks it up and to his shock their were blood written letters that said 'WHY AM I A MISTAKE?!".
Tony dropped the letter in utter shock, then a piercing screamed filled his ears he looked around him but found no one there. From this moment Tony knew that something was going on.
Oh how right he was, wherever he went the horrible smell followed, things moved on their own like a salt shaker at some dinner that he stopped by it moved and dropped right on his lap, the top open and spilled on him. And to make it worse the waiter thought he did it himself and said he had butter fingers.
Then finally one night while Tony was in another motel's bathroom he was washing his face, and when he looked up at the mirror and saw a battered, twisted neck version of his brother standing behind him while looking at him angrily.
Tony jumped and turned around only to see that no one was there, it was at that moment Tony now knew that ghosts were real and his brother and his friends were haunting him.
There years later Tony settled down in Mondo A GO! GO!, but the activity has gotten worse the smell has gotten so bad that it made Tony want to puke, things were being placed in areas that he didn't want them to be, and worse he actually been punched in the face while he eating his lunch. Sometimes things were actually thrown at him like a microwave that flew off the counter and smashed into the wall just inches from his face.
Then one night while he was sleeping Tony woke up to an agonizing pain on his chest, it felt like he was being stabbed multiple times he also feels a rope go around his neck and strangle him along with the feeling of being beaten. The next morning when he looked in the mirror he found cuts on his chest, a bruise on his neck, and two black eyes.
And so Tony was doomed for eternity, the sprits of Ed, Edd N Eddy haunt him where ever he goes, attacking him at pure random and they will not rest until he dies. Which would be soon as he would die after a mysterious car crash.
